This makes for ease in transportation and handling of the building material of this invention.

Figs. 4 and 5 illustrate another modification in which the final structure is rigid in all directions. As in Figure 1, the same base material I, reflecting metallated surface 2, ridges 3 and rigid metal strips 4 are provided. Metal rods or wires 1 are arranged lengthwise of the material at spaced intervals across the metal strips 4 and are joined to the strips at points 8 by spot welding or any other suitable means of attachment. The wires I and strips 4 in this case serve as the plaster key.

The modification shown by Figs. 6 and 7 is similar to that of Figs. 4 and 5. The strips 4 in this case are made appreciably taller in cross section than the ridges 3. This provides a space above the ridges 3 so that the rods or wires 1 may pierce the strips l as indicated at 9 without piercing the ridges 3. The rods 1 may be welded or otherwise secured to the strips, if desired.

In both modifications shown by Fig. 4 or Fig. 6, the winged strips of the type shown by Fig. 3 may be used. The wings would thus provide additional keys for the plaster.

It will be noted that in all of the above constructions there is no piercing of the base material l 01 the metallated surface 2. Thus, it will be seen that if the base material is of a character that can prevent the seeping through of the plaster or water during the time that that plaster is applied and during the drying period, then the metallated reflecting surface will not be tarnished or corroded in any way.

The structure shown by Fig. 8 is one which is to be employed as a structural material where insulation only is required without the need for a plaster base. The base material ill is the same as in the other modifications. This is provided with a metallated reflecting surface II on one side and a similar surface l2 on the other side. The ridges I3 and strips H are the same as in Figure 1. Thus, there is provided an insulating structural material that is rigid in one direction and so may be more readily handled during its application.

If rigidity .in such an insulating material is desired in all directions, a construction like that shown by Figs. 4 and 6 may be employed.

The metallated building material of this invention finds utility in many places in a building structure, where heat insulation is required and where a plaster or stucco base and effective key therefor, as a substitute for ordinary lath, is required.

In an ordinary exterior wall, the material of this invention would be nailed to the spaced uprights with the metallated surface facing the air space in the wall. The other side faces the inside of the room and is immediately ready to receive the plaster for finishing the interior wall.

On the outside of an exterior wall, if it is to function as a base for stucco, the material of this invention would be nailed to the spaced uprights with the metallated surface facing inward toward the air space. The other side would face the exterior for receiving the stucco.

This invention may also be used similarly on ceilings and on the inside of the roof structure.

When insulation only is required, the construction shown by Fig. 8 would be used. The stiffening rods crimped to the two sided reflecting surfaced sheet would aid in positioning and handling it during erection.

It is thus seen that I have invented a material of construction that is a marked improvement over that heretofore used. It will not lose its insulating efficiency when it is in place and will act as a plaster base to retain the plaster in position more effectively than the material heretofore used.
